grails で単体テストを実行できません。以下のようにテストしたいメソッドを備えたTransactionController(githubでも入手可能)があります。transactionAnalytics
TransactionController.groovy
package eccount
import org.codehaus.groovy.grails.web.json.JSONObject
import org.springframework.dao.DataIntegrityViolationException
import grails.converters.JSON
class TransactionController {
def transactionService
def transactionAnalytics = {
searchRequest = searchRequest ?: new SearchRequest(requestParams: new HashMap<String, String>())
configureRequestParams()
def responseBytes = transactionService.getSearchResponse(searchRequest)
def jsonResponse
if (responseBytes)
jsonResponse = JSON.parse(responseBytes)
else
jsonResponse = new JSONObject()
render jsonResponse as JSON
}
}
対応するテストTransactionController#transactionAnalytics
( github でも入手可能) は以下のとおりです。
TransactionControllerTests.groovy
package eccount
import org.junit.*
import grails.test.mixin.*
@TestFor(TransactionController)
class TransactionControllerTests {
def INDEX_NAME = "gccount"
void testTransactionAnalytics(){
Map<String, String> params = new HashMap<String, String>()
params.put("indexName",INDEX_NAME)
//println params.get("indexName")
//controller.params = params
controller.params.indexName = "gccount"
controller.transactionAnalytics()
def jsonResponse = controller.response.json
println jsonResponse
}
}
コントローラーのメソッドを実行すると、次の例外が発生します

とにかく、ここで実際に null になっているのは誰ですか?
